This study presents an integrated model of maintenance and statistical process control
(SPC) for a production process with three states (in-control, out-of-control, and failure). The …

With the continuous improvement of machine performance, the multifunction machine has
gradually become the first choice of many enterprises. Due to the usage and wearing of the …

In this paper, a condition-based imperfect maintenance model based on piecewise
deterministic Markov process (PDMP) is constructed. The degradation of the system …

The main purpose of this paper is to schedule an imperfect maintenance policy for a single
unit multi-state system (MSS) exhibiting more than two output states in the duration of its …

Since its introduction, the geometric process (GP) has attracted extensive research attention
from authors in various research communities, including probability, statistics, and reliability …

This paper proposes a maintenance model for a Proton-Exchanged Membrane Fuel Cells
system. Two types of failures are considered: non repairable internal failures and possibly …

Maintenance policies are crucial for ensuring the reliability, safety, and longevity of a system,
as well as reducing the risk of accidents. Preventive maintenance (PM) is an effective …

We consider a shock and wear model in which the inter-shock arrival process is a phase-
type (PH) renewal process, and the system's lifetime is generally distributed. The system has …

An alternating geometric process can be used to model the operational and repair times of
an ageing system. In applications such as warranty cost analysis, the mean of an alternating …

The geometric process has been widely studied in various disciplines and applied in
reliability, maintenance and warranty cost analysis, among others. In its applications in …
